Application fled my 24, 1988. Serial Ito. 841,044.

. March 28th, 1923, Serial No. 628,183, and

over which this present invention is an improvement, the same beingdesigned especially for military use and for such purposes as bombing,as distinguished from the conveyance of passengers or freight as referre to more particularly in the previous 'ap lication.

or the convenience of any reader of both specifications the principalparts of the present construction areindicated b reference characterscorresponding to simi ar parts of said previous case.

Among the principal objects of the present improvement are thefollowing: to provide an aeroplane with a peculiar propulsion means inthe nature of tubular passageways equipped with powerful blower fans forthe forward traction of the machine, either in connection with orseparate from traction propellers as set forth in the previous'application, and to provide im roved tubular passa ways'and powerfullower fans for assisting at least in the elevating or vertical controlof the machine.

In the accompan ing drawings in which the several principa parts arereferred to by like reference numerals,

Figure 1 is a plan view of the main parts of my improvement.

Fi 2 is a front elevation of the same.

Re errin now more specifically to the drawings would dcscribebriefly theprincipal arts similar to those in the parent ap plication, to lay abasis for the special description of theimproved features. The

body may be variously constructed and shaped and sub-divided if. desiredfor the storage or conveyance of the ammunition or implements of warfareaccording to the purpose of the machine. Access may be had to theinterior of the body over rails or steps 29 and through a door-way 30.Windows are indicated'at W, and these of course may be variously locatedas" desired. are vertically arranged power operatedshafts upon which aremounted helicopter or 'lifti'n' propellers 51'. Traction propellers 53are s own mounted at the front portion of the machine on shafts 54driven from motors 55 suitably located in relation to hollow buo antliftin and sustaining planes 56, 57, an 58 exten mg laterally across'andfrom the sides of the body.

Lateral direction controlling means includes a rudder swung from avertical axis 66 and preferably through lines 67 extending along thebody. Elevator planes are indicated at 69 above the uppermost main frontplane 56, and toward the rear of the body are located one or moreauxiliary planes 73. At the bottom of the machine are arranged tractionshoes 33 having tires 37 and connected through hangers 40 asspecifically setforth in the previous ap lication, and at or toward theends of the lbwermost plane 58 are pontoons 75. I

The vertical blower controlling means above referred to are indicated asincluding a plurality of vertically arranged cylindrical tubes 89 inwhich are located power operated blower fans 90. With these fanssuitably driven the machine will be lifted or controlled in its verticalmovements and by the reversal of the fans in one or the other of thetubes the vertical steering of the machine may be manipulated. It willof course beborne in mind that the upper com artments of the body aswell as the planes t emselves are of hollow construction and chargedwith suitable buoyant gas such as helium or hydrogen.

The principal features of novelty of this specification are thehorizontal tubes or passage-ways 92 located on opposite sides of thebody andparallel to each other and to the longitudinal axis of the body.Each of these passage-ways is .indicated, especially in Fig. 2, as bui tabout one-half into the contour of the body, and the other half on theoutside thereof. In these passage-ways are mounted powerful blower fans93 on shafts 94 driven from motors 95 mounted at any convenient Ipace,as for instance, upon the top of the dy Belts 96 operate by tween themotors and the shafts. It is estimated that these fans of say ten feetin diameter when run at a speed of 209 R. P. M. will displace througheach of the passageways 92 eighty-eight thousand cubic feet of air perminute, a condition which will powerfully influence the forward movementof the machine, whereby the operation thereof with-respect to the enemysposition may be exceedingly rapid.

I claim:

1. In an aeroplane of the type setforth,

the combination of a body, elevatin and ele- Ways extending alon 'vatingcontrol-ling means co-o rating therewith, a pair of cylindrical tu ularpassagethe body on 0 site sides,. thereo f and bui t partially wit 1nthe contour of the body, powerful blower fans mounted in saidpassage-ways on horizontal fore and aft axes, and means to control therotation of the blower fans.

2. Mechanism as set forth in claim 1 in which the tubular passage-waysare two in number and mounted on the sides of the bod on the same leveland are built substantial y one-half of each within the contour of theside of the body, while the other half is convexed outward therefrom.

In testimon whereof I afiix my si ature.
